Release Notes for 441

I would instinctively do something like

for i=1, #data, 8 do
    local a, b, c, d, e, f, g, h = string.byte(data, i, i + 7)
    freq[1 + (a or 256)] += 1
    freq[1 + (b or 256)] += 1
    freq[1 + (c or 256)] += 1
    freq[1 + (d or 256)] += 1
    freq[1 + (e or 256)] += 1
    freq[1 + (f or 256)] += 1
    freq[1 + (g or 256)] += 1
    freq[1 + (h or 256)] += 1
end

Although using two loops to avoid or might be slightly worthwhile.
